SMITH ADMINISTRA CLAMP F131; IRE STRETCHERS.

Application filed July 6,

West Virginia, have invented ce 'tain new and useful Improvements 1nClamps IorlVire Stretchers, of which the following is a'spe'cification.i This invention relates to improvements in clamps for use in connectionwith wire ,stretchers. V

The primar object of the invention is the provision of a clampadaptedfor specific use in connection withstretchers' ofreticulate orwoven wire mesh, embodying but few parts, so related as to provide, asimple, efficient and easily operated-clamp.

A further object of the invention is the provision of a clampspecifically embodying a'pair of clamping aws, one of said jaws having ashoe attached thereto to detachably receive the other clamping aw, andembodying an adjusting means for use in connection with the shoe tosecurely clamp the jaws to a fence.

Other objects and advantages will be apparent during the course of thefollowing detailed description;

In the accompanying" drawing, forming a part of this specification,and'in which similar reference characters designate corresponding partsthroughout the several'views. Figure 1 is a perspective view of a fence,having a clamp attached thereto.

In the drawings, wherein forthe purpose of illustratlonxis shownthepreferred embodiment of my invention, the letter 'A desig-f nates aclamp'for use in connectionwith a reticulate, or woven-wirefence B.

The clamp A preferably comprises a clamp aw or member C having a shoe Drigidly attached thereto. A second clamping j aw or member E is adaptedfor detachable reception within the shoe D. The members C and E areprovided with an adjusting means F for use in'conneotiou with the theslot QOof-the post' 11, and for a 15:21. Serial No. 482,743.

shoe D, to maintain the j aws in position to engagea fence.

The members C andE are preferably formed of hard wood posts 10 and 11respec 'tively, and each substantially rectangular information. The post10 is provided ad jacent to one end with the shoe D, said-shoe D beingpreferably J-shaped in formation, and formed of band iron. The longerstem 12 of the shoe D is preferably afiixed near its free end to anouter side 13 of the post 10, as by a -bolt 14 -e::tending transverselythrough'said post. The bight portion 15 of the shoe Dextends overtheextreme end of the post 10, and the same being greater in thickness thanthepost 10, to provide a portion ofsaid bight section projectinglaterally from the post 10, to provide, together with the" upstandingshort-er .stem 16 a pocket structure 17. The stems "12 and 16, are preferably in parallel alignment, and spaceda sufiicient distance by thebight portion 15, to

- provide the pocket 17 of just sufficient width to freely receive anend of the second jaw member E! A bolt 18 is detachably positionedtransversely through the post 10, being of greater length than the bolt1d, so as to engage the two legs or stems 12 and 16 of the shoe D. It ispreferred that the bolt 18 extend parallel with the bight section 15,

and spaced a pre deteri'nined distance theredetachably afiirted, asby'scr ews 23, to the outer surface 25, of the post 11, and-1scountersunk injthe outer surface 25.

j The plate 22, is slated at an end, in order to align with purpose tobe subsequently set'forth. j

The adjusting means F isprovided for varying the relative position ofthe jaws G and E the same being preferably positioned upon said awsremote from the shoe D. Apertures 27 and 28, are provided transverselythroughthe posts 10 and 11 respectively,and adapted to align when thejaws C and E are in clamped position. Plates 29 and 30 are detachablypositioned,as by screws 33, eXteri orly upon the outer surfaces 13 and25, of the posts, 10 and 11 respectively, and in such positionthat thebore 31 of the plate 29 and screw threaded aperture 31 of the plate 30respectively align with the bores 27 and 28 of the posts and 11.

A screw threaded bolt 34 is provided 7 for use in connection with theplates 29 and '30, for insertion through the bore 31 of the former andfor engagement in the screw threaded aperture of the latter, tov advanceor retract the C'and E; a

37 and 38, similar to the strip 36, are positioned upon the longitudinaledges of the inside face of the post 11. The strips 36, 37, and 38 arerelatively narrow, and are so positioned for cooperation on the posts 10and 11, as to be spaced from each' other, when the abutting insidesurfaces of the posts 10 and 11 are in clamping position.

In operation, the jaw C is positioned substantially vertical upon asection of the fence B. The adjusting bolt 34, of course, having beenunscrewed from the jaw E, and preferably adjusted as not to project fromthe inside face of the post 10. The next-operation, is to position thepost 11 in the pocket 17, as provided by the shoe l) and in suchposition that the vertical slot engages over the portion of the bolt 18,which projects transversely through the pocket 17. l l hen the post E isin this position'in the pocket 17, said jaw will beprevented frompulling away fron the jaw C or from slipping laterally therefronnbyreason of the bolt 18, and the shorter stem 16. The posts 10. and '11are then moved relatively together, until theg3 are properly positionedupon the fence In this position, the openings 31 and 32 of the plates 29and 30 respectively are inalignment. The adjusting bolt 3a is thenmanually rotated by the operator until the same engages through thescrew threaded opening 32 of the. plate 30.. The belt 3a is tightlyadjusted in the jaws and E, firmlyforeing said aws' together,in suchmanner that the various strands of wire of the fenceiB are crimped bythe strips 36,

37, and 38, substantially as illustrated in Fi ure 5 of the drawin andthusi. reventa: .CJ7 p ing the clamp A from disengagement with the fence1%., 1

Various changes in the shape, size, and er rangement of parts, may bemade in the form the invention herein shown and de-' scribed, withoutdeparting from the spirit of the invention or the scope of the claims. qr
